Improving the performance of a biofuel cell cathode with laccase-containing culture supernatant from Pycnoporus sanguineus.
Laccases are multicopper oxidoreductases that can be used in biofuel cells to improve cathode performance by cathodic oxygen reduction. Here we present a laccase from the ligninolytic white-rot fungus Pycnoporus sanguineus that, in contrast to the Trametes versicolor laccase, can be produced in the absence of inducers in a standard culture medium. After 7days of cultivation the activity of this...
متن کاملA laccase–glucose oxidase biofuel cell prototype operating in a physiological buffer
Here we report on the design and study of a biofuel cell consisting of a glucose oxidase-based anode (Aspergillus niger) and a laccasebased cathode (Trametes versicolor) using osmium-based redox polymers as mediators of the biocatalysts’ electron transfer at graphite electrode surfaces. The graphite electrodes of the device are modified with the deposition and immobilization of the appropriate ...
متن کاملDesign and Fabrication of Glucose/O2 Enzymatic Biofuel Cell
Enzyme-based biofuel cells (EBFCs) are systems that use a variety of organic compounds to produce electricity through oxido-reductase enzymes, such as oxidase or dehydrogenase as biocatalysts immobilized on electrodes. In this study, a single-chamber EBFC consisting of carbon electrodes that operating at ambient temperature in phosphate buffer, pH 7 is reported. The EBFC anode was based on gluc...
متن کاملFabrication of Mediatorless/Membraneless Glucose/Oxygen Based Biofuel Cell using Biocatalysts Including Glucose Oxidase and Laccase Enzymes
Mediatorless and membraneless enzymatic biofuel cells (EBCs) employing new catalytic structure are fabricated. Regarding anodic catalyst, structure consisting of glucose oxidase (GOx), poly(ethylenimine) (PEI) and carbon nanotube (CNT) is considered, while three cathodic catalysts consist of glutaraldehyde (GA), laccase (Lac), PEI and CNT that are stacked together in different ways. Catalytic a...
متن کاملZinc tetraaminophthalocyanine-Fe3O4 nanoparticle composite for laccase immobilization
Zinc tetraaminophthalocyanine-Fe3O4 nanoparticle composites were prepared by organic-inorganic complex technology and characterized. It has been proved that the ZnTAPc dispersed randomly onto the surface of Fe3O4 nanoparticles to form molecular dispersion layer and there was a relatively strong bond between central zinc cation and oxygen. The nanoparticle composite took the shape of roundish sp...
